"BlackBerry offered few signs of a long-promised turnaround on Friday, with an unexpected quarterly operating loss, a dearth of details on sales of its make-or-break new line of devices and no return to profit expected in the current quarter. BlackBerry shares tumbled about 28 percent in both U.S. and Toronto trading." 'Unexpected'? Really?

Given that Visual Studio licenses cost between $700 and $12 000, unless you are a Microsoft partner, then I think it is only fair for developers to complain if they are now expected to buy a new version per year.
